IMPROVEMENT IN CAMERA-STANDS.

To all whom t may concern:

Be it known that l, J. WV. HARPER, of Gleveland, in the county ot' Cuyahoga and State ot' Ohio, have invented certain new and useful Improvements in Camera-Stands; and I do hereby declare that the following is a full and complete description ofthe same, reference being had to the accompanying drawings, makingapart ot' this specification, in which- Figure l is a side view ot' the stand. Fig. 2 is an end view. Fig. 3 is a view of the side opposite from Fig. l. Fig. 4t is a sectional view.

Like letters ot reference refer to like parts in the difterent views.

My improvement relates to a cainerastand for thepurpose ot' adjusting the standhorizontally and vertically, as hereinafter described.

A represents the trame of the stand, that consists ot' a table, B, to the frontot' which is secured a standard, B', and from the rear end extend down legs b I), fastened at the lower end in a cross-piece, b. Underneath the crosspiece b and standard B are casters a, as represented, i'or moving the stand around.

In the standard B and front part ot' the table there is a slot or opening, e, in which there is a ratchet-wheel, D, hung at c to the frame or standard, in the teeth of which a pawl, d, works, that is pivoted at c to the table.

G is a handle secured in the edge or rim of the ratchet-wheel, by which the wheel is turned so as to raise or lower the stand. ffare guides on the sides ot' the table or frame, in which a moving frame, H, slides. This trame is of a rectangular form, as shown in Fig. 2, and fits into the guides fou the sides, whereby it is retained in a vertical position as it is moved up and down.

To the lower end of the frame, at o', is attacheda strap, J, that extends up onto the rat- Chet-wheel, as seen in Fig. 4, and is attached at the end to it. From the sides of the moving frame, at the top, extend up lugs I), to which is hung a platform, L, so that it can be inclined either way, as indicated by the dotted lines in Fig. 3, and it can be secured at any inclination by means of' a slotted segment, N, attached at the ends to one side of the platform, through the slotN of which a thumb-screw,m, extends into the frame, which can he screwed or tightened on the plate N, so as to hold the platform in any position.

The stand or platform Lis raised or moved upward by simply turning the wheel D or moving it down by the handle g, the pawl slid ing on the teeth, and when the pressure is released from the wheel the pawl catches into the teeth and holds it in that position.

To lower the stand, simply press on the upper end ot' the pawl at d', when the catch will be released from the teeth on the wheel, and the weight ot' the stand will cause it to slide down, and, allowing the pawl to catch into the teeth, will retain it in any position.

This stand is very simple in its construction, and can he adjusted with the greatest ease and facility.

There is a rim or ledge around the top ot' the platform by which the camera is held in place when adjusted for taking the picture. And by means ot` the sliding frame it can be moved up or down and inclined in any position that may be desired for taking the picture.

What I claim as my improvement, and desire to secure by Letters Patent, is-

The frame H, adjustable platform L, and segment N, in combination with the ratchetwheel D and strap J when operating conjontl y, as and for the purpose set forth.
